I have 2 female doxies. one is a silver dapple and the other is a isabella dapple. I'm looking for advice in getting a male for breeding.

I don't want to create any health issues, and want to have healthy babies. I need advice on what color of a male I should be searching for to breed with my baby girls. I understand that I don't want any dappling in a male, but do I also want to avoid piebald, and are there any colors I should avoid? I have found a male blue piebald, would that be acceptable or will that cause skin problems?
